TROPICAL STORM ALBERTO DISCUSSION NUMBER 77
NATIONAL WEATHER SERVICE MIAMI FL
5 AM EDT WED AUG 23 2000
JUST WHEN IT LOOKED LIKE ALBERTO WAS HISTORY...IT DEVELOPED A LITTLE
BURST OF COLDER CLOUD TOPS...AND THE TROPICAL CYCLONE LIVES ANOTHER
6 HOURS. ALBERTO IS THE THIRD-LONGEST LASTING ATLANTIC TROPICAL
STORM ON RECORD...BEHIND GINGER OF 1971 AND CARRIE OF 1957. SHOULD
IT LAST ANOTHER 12 HOURS...WHICH IS NOT LIKELY...ALBERTO WILL TIE
CARRIE.
THE EYE IS NO LONGER APPARENT ON INFRARED IMAGERY...AND THE
CONVECTION IS BECOMING ELONGATED. THE INITIAL MOTION IS NOW 045/40.
WITH WATER TEMPERATURES NOW BELOW 15C...IT IS HARD TO BELIEVE THAT
ALBERTO CAN MAINTAIN TROPICAL CHARACTERISTICS FOR MORE THAN A FEW
MORE HOURS. THE OFFICIAL FORECAST FOLLOWS THE AVN TRACK USING THE
CURRENT FORWARD SPEED.
